Verify download complete?

[StewardManscat]

Thanks to this forum, I have built the code to download files and resume broken downloads (http Accept/Range stuff).

Currently access to downloads is controlled by a timer.

I'd prefer to allow unlimited time, but shut off access once the download is complete.

Anyone know of a way to do it? How do we know if all bytes were received?

Currently:

if DownloadFile("blah")
logging("download complete")

DownloadFile($filename) {
//set http range headers etc
...
fpassthru($fp);
return true;
}

I get the log entry seconds after the download starts (php create another process to do it?). Same with seek... echo fread($fp,$sendSize) instead of fpassthru.

If the download is paused and resume 3 times, I get 3 log entries. Maybe the customer got the file, maybe not.

I can tell what I sent. Can I tell what was received?

Many thanks in advance.

I saw a javascript/php progess bar somewhere, sorry I don't remember where.

That presupposes the ability to tell how many bytes have transferred, so if you find that app it might have the answer you're looking for
